Abstract

OBJECTIVE

To report the hearing results following type III cartilage "shield" tympanoplasty.

STUDY DESIGN

Retrospective chart review at a tertiary referral center.

METHODS

Conchal cartilage, shaped as a shield, was used to replace the entire tympanic membrane and reconstruct the ossicular chain in patients with an absent incus and diminished space between the stapes superstructure and malleolar manubrium.

RESULTS

Between January 1998 and June 2005, 52 patients were treated. The mean age was 32.4 years (range, 7 to 72 years). The mean follow-up was 24 months (range, 12 to 36 months). Graft take was successful in all patients. The average hearing improvement was 11.22 dB (P<0.0001). An air-bone gap of 25 dB or less was achieved in 41 (78.8%) patients. Speech discrimination scores remained unchanged. No complications were identified.

CONCLUSION

Type III cartilage "shield" tympanoplasty is an effective technique for hearing improvement in selected patients with chronic otitis media. The results of this procedure are similar to those obtained with partial ossicular replacement prosthesis.

摘要

目的

报告III型软骨“盾牌”鼓膜成形术的听力结果。

研究设计

在三级转诊中心进行回顾性病历审查。

方法

对于砧骨缺失且镫骨上部结构与锤骨柄之间间隙减小的患者，使用塑形为盾牌状的耳甲软骨替代整个鼓膜并重建听骨链。

结果

1998年1月至2005年6月期间，共治疗52例患者。平均年龄为32.4岁（范围7至72岁）。平均随访时间为24个月（范围12至36个月）。所有患者的移植物均成功存活。平均听力改善为11.22 dB（P<0.0001）。41例（78.8%）患者的气骨导差达到25 dB或更小。言语辨别分数保持不变。未发现并发症。
